1. The Darius Wade issue. Wade had a season ending leg break in the Florida State game. Losing your starting QB is always a tough blow. But Wade has done nothing since to validate Addazio's decision to build the season around him. Addazio admitted that he did not bring in a transfer and was ready to go with his homegrown QBs (Wade, Flutie and later surprisingly Jeff Smith and John Fadule). Even if Wade stays healthy, does the season become a success? I think Addazio doubts it because he has had numerous chances to put Wade back on the field and hasn't. In hindsight, it seems like Addazio entered the season without a good idea of what he had at QB. That's not good coaching or roster management.
2. BC only won three games despite having the best defense in the country. When one side of the ball is that good, you just have to be competent in other aspects of football to win even a few games. Addazio didn't. A good coach would have done some triage to the roster and offense to put together some sort of simple, winning game plan for a few of the games.
3. BC finished 1-5 in games decided by seven points or less. This speaks to Addazio being a poor game manager and not just unlucky (although luck is a factor in close games). The Wake Forest game was epic mismanagement. The Duke game was too as he kept Flutie in way too long. The Syracuse game also saw BC squander a late tie against a bad Syracuse team with a fired coach. If Addazio flips two of those games and closes out the near upsets of Notre Dame and Louisville, his job is safe now.
4. 2015 was the first sign that Addazio had real issues managing his offensive staff. As I have said, when you are the worst at one aspect of something, it is a complete failure in how you plan, how you practice, how you teach, how you evaluate, and how you work together. We were a complete grab bag of styles and players and approaches. BC started four QBs that year who have little in common other than their uniforms. I don't know what Addazio was trying to be. I don't know if Todd Fitch did either because he was shown the door after the season. Now if that season was just a one-time issue, I would buy into the "lost" narrative. But Addazio has yet to stabilize that side of the ball. Was last week's outburst a turning point? We will see. Right now it looks like an aberration.
5. Even Spaz didn't have a winless ACC season. And Addazio's only won three ACC games since. That is not lost. That is a pattern.
